Newspaper clips of patent applications are dated from 1906-14, and are all from areas of Nevada. This ledger was immaculately kept, and preserved nicely. I acquired this from the son of the man who discovered the Goldfield Mine, in Goldfield Nevada, He sold other items from this collection a few years back to the San Francisco Museum. There are also claim slips from different mines in Nevada. Very interesting piece of mining history! If you have anything to add it is appreciated :)
